Cell phone ownership among teens ages 12-17 increased from 45% in 2004 to 75% in 2009. Texting has become a primary communication method, with 72% of teens owning a cell phone and 54% texting daily as of September 2009.

Gender disparities: Girls are more active texters than boys, with older teen girls using their phones most frequently for texting and voice calls. Girls also sleep with their phones more often.

Key communication uses: Texting is used extensively for socializing (e.g., greeting friends, coordinating meetups), sharing private information, schoolwork, and entertainment. Girls are more likely than boys to use texting for these purposes.

Regulating use: Parents monitor 64% of teens' phone usage (checking contents, limiting minutes/times, monitoring location, and taking phones away), especially for younger teens and girls. But few parental restrictions reduce certain negative behaviors significantly.

Safety concerns: Driving while using mobile phones (both talking and texting) is reported by 34% and 52% of teen cell owners respectively. Sexting remains an issue, with 15% of teens receiving and 4% sending inappropriate content. About 26% experience harassment via phone.
